Address Space Layout Randomization

First added

  • with iOS 4.3

Program and dyld

  • On program load, the address space offset of the program is randomized between 0x0 and 0x100000
  • It always falls on a 0x1000 page boundary
  • dyld is included in this sliding section


  • The system libraries are now stored in a big cache file, see [[1]]
  • This is address randomized at boot time, in many possible places
  • The functions retain a fixed offset to each other.
